IMPROVEMENT IN WATER-METERS.

Specification forming part of Lettrrs Patent No. l7 6,07S, dated April11, 1876 ;applica.tion filed January 24, 1876. i

To all whom it may concern:

Be it known that I, AUGUSTUS SEQUEIRA, of the city and county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Water-Meters; and to enable others skilled in the art tomake and use the same, I will proceed to describe, referring to thedrawings in which the same letters indicate like parts in each of the tigu re s This invention relates to certain improvements in water-meters;and consists more particularly in the peculiar construction of thepiston having no actuating rod or other fixture attached thereto, andits combination with compound valves in the other chambers of the meter,whereby a regular and automatic action of the device is insured withoutthe intervention of any mechanical motor, all as will now be morespecifically and in detail set out and explained.

In the accompanying drawings, on Sheet 1, Figure 1 is a top view of themeter. Fig. 2 is a side view, showing a section through the line E F, onSheet 2. Fig. 3 is a vertical section through the line 0 D, on Sheet 2.Fig. 4 is a vertical end section through the line A B, on Sheet 3,showing the end of the piston in its cylinder. and the ends of twovalves in their chambers. On Sheet 3, Fig. 5 is a side view, showing oneof the valves, its chamber, and ports leading to and from the same. Fig.6 is a horizontal section through the line G H on Sheet 2.

a is the cylinder, in which the piston 1) vi brates. a and a are valvechambers, in which the valves a and a are fitted to play closely andfreely therein. The piston 12 and valve a are provided with hubs ordetents so on each end, which strike their respective heads eachalternate motion, and by which the desired and exact amount of play isregulated, and determine or fix the accurate measurement of fluid. Thevalve or is provided with lugs h, which extend through and play in slitsformed in or through the cylinder, directly under the seat of the valveto, against which the end of piston b strikes, and move it so as to openalternately the ports.

The operation is as follows: The Water is first introduced into themeter through the induction-orifice c, and upward through properlv-formed passages to the top of valve-chamber a; thence right and leftthrough ports at d into compartment 0; thence down through passages toport f, and into cylinder a, be tween the head of the cylinder and theend of the piston 11, and by its pressure moves the piston to theopposite end of the cylinder, and

in its movement it strikes the lug h in the valve a, and moves it in thesame direction with the piston, and opens the port 70, which leads intoportj, and allows the water to pass directly into the valve-chamberbetween the head and end of the valve a and moves it forward to theopposite end of its chamber, and forces the water from the chaznberthrough passages to the discharge n, and in doing so the water entersthe compartment 0; thence through the ports f between the cylinder andpiston-heads, and, by the pressure of the water, the piston is reactedto the opposite end and drives the water through port f and compartmentc, and through the discharge-passage out at port a, and vice versa, acontinuous action and steady discharge will be produced.

The dial for registering the measurement of fluid forms no part of thisinvention.

Having thus described the construction and operation, what I claim, anddesire to secure by Letters Patent. is-- 1. In a water-meter, thesliding balancevalve a with its heads I II III IIII, and detents x,operating in and combined with chamber 60 substantially as and for thepurposes set forth.

2. The piston I), having detents m, and operating in chamber a, incombination with "alve a, having lug IL, substantially as and for thepurposes set forth.

3. Th'e combination of cylinder a, having piston I), provided withdetents a, and valve chamber a having the valve a, lug h, with chamber ahaving valve a substantially as and for the purpose set forth.
